van den Brink MJ, et al. - Researchers investigated if women with heavy menstrual bleeding (HMB) have a preference for treatment characteristics (procedure performed by gynaecologist or general practitioner; reversibility of the procedure; probability of dysmenorrhea; probability of irregular bleeding; additional use of contraception; Need to repeat the procedure after five years; and treatment containing hormones) of the levonorgestrel intrauterine system (LNG-IUS) or endometrial ablation. The relative importance of these characteristics was also assessed. The most important characteristic influencing patient treatment choice for HMB was whether or not a treatment contains hormones. Characteristics that were related to endometrial ablation were mostly preferred. However, the participants were willing to trade off between characteristics.
